Canvas, how do you dye it?

[rob love]

I have done a bit of that work, but I found you had to dye the material before sewing it, otherwise the seams would not take the dye. The material would stretch the seams a bit and you would have shadows of the lighter colour.

The dye I used required the water to be very very hot. Not sure a washing machine would do the same. Also not sure the next person to use the machine after you would be very happy to have all their unmentionables turn olive drab.
